LOS ANGELES -- The news wasn't as terrifying as the day before, when it was announced reigning National League Cy Young winner Clayton Kershaw would miss his Sunday start in San Diego because of a muscle pull in his back, but the nicks continue to pile up for the Los Angeles Dodgers, something that hindered the club down the stretch last season.Dodgers manager Don Mattingly revealed before Thursday's exhibition game against the visiting Los Angeles Angels that second baseman Alex Guerrero had strained the intercostal muscles that run along his ribs, sidelining him indefinitely.
